Achieving employment compliance was crucial as the industry geared up to anticipated large-scale extra planting under the new government's billion-tree target, he added.
"Not many extra trees will be planted in 2018. However, when the new planting load comes on in 2019, with many hundreds of extra planters, we have to have our employment side fully compliant with the law," he said.
Mr Clark noted that forest companies had been backing the recently begun Forest Industry Safety Council Safetree Contractor Certification scheme. To gain certification, a contractor had to provide documentation to prove they were labour law-compliant.
"Sixty-nine companies are already working through the process, which will result in a much more transparent industry," he said.
